Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern is repeated throughout the circumference of the tire tread, the opposite side being the same as that illustrated; and,

FIG. 2 is an enlarged fragmentary front elevation view of the tread pattern of FIG. 1 showing our new design.

The broken line disclosure of a tire bead and sidewall is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
